An increase in a wave's amplitude will result in an increase in its energy or intensity. The amplitude of a wave is a measure of the maximum displacement or distance of a particle in the medium from its rest position. In the case of a transverse wave (e.g., light or electromagnetic wave), the amplitude represents the maximum height or depth of the wave. In the case of a longitudinal wave (e.g., sound wave), the amplitude represents the maximum compression or rarefaction of the wave.
When the amplitude of a wave increases, it means that the wave is carrying more energy. For example, in the case of a sound wave, an increase in amplitude would result in a louder sound because the increased energy causes greater variations in air pressure. Similarly, in the case of an electromagnetic wave, an increase in amplitude would result in a brighter light or a higher intensity of the wave.
However, it's important to note that increasing the amplitude of a wave does not change its frequency. The frequency of a wave represents the number of complete cycles or oscillations it completes in a given time.
